While some models of ThinkPad can charge by their USB-C port, there are many that can only be charged via the yellow rectangular power socket, referred to by Lenovo as “slim tip”.

The result being you may end up carrying two chargers around with you… a hefty ThinkPad brick with a mains plug and a compact USB-C charger for your other devices.

Recent advances in the USB-C specification allow for higher power USB-C charging.

This means you can replace the bulky ThinkPad charger with a more versatile USB-C one and embrace a lighter charging solution.
